To all whom it may concern:

Flatbush, in the county of Kings and Stateof New York, have invented anew and ImprovedLubricating Compound; and I do hereby declare thefollowing to be a full, clear, and exact description thereof, which willenable those skilled in the art to make and use the same.

This invention relates to a compound of tallow, petroleum, caustic soda,and animal hair, which ingredients are mixed together to a thick pastymass, in such a manner that on applying the compound to a journal, thehair will prevent the grease from heating, and as said hairs are drawnout endwise by the traction of the journal they will, by their capillaryattraction, carry a sufficient supply of the lubricating material to thejournal to keep the same in order for a long time without requiring anyattention.

In preparing my'compound, I take the abovenamed ingredients in about thefollowing proportion: tallow, ten parts; petroleum, (by preference theheavy oil,) three parts; caustic soda, one part. After these ingredientshave been thoroughly mixed I add thereto a quantity of animal hair, moreor less, according to the journals for which -the lubricating compoundis to be used.

My compound forms a thick pasty mass, and if it is applied to a journalthe hairs mixed with it are immediately drawn out, so that the same willact in the capacity of small tubes,
